Technical overview
Model AST-17D scuba diving O2 sensor replaces Teledyne ClassnR-17D and R-17S, AII Model PSR-11-39-JD, Vandagraph R-17VAN and Nuvair 9507 O2 sensors. The AST-17D scuba diving O2 sensor is a galvanic type micro fuel cell specific to oxygen. It provides electrical connection via a 3.5mm mono jack. The external sensor casing has M16x1 thread front end. Expected sensor life is 42 months under ambient temperature and pressure. Proprietary electrolyte formulation and anode geometry ensure full utilization of Pb anode, thus providing longer life without signal drift and minimizing periodic calibration requirement. Sensor is designed, developed and manufactured in the USA.
Applications and guidance
Advanced Sensor Technology
The AST-17D scuba diving O2 sensor is a galvanic micro fuel cell specifically engineered for oxygen detection in scuba diving and rebreather systems. Because accurate oxygen monitoring directly affects diver safety, this sensor delivers stable signal output, fast response, and long operating life in demanding underwater environments.
Replacement for Multiple Scuba Diving Oxygen Sensors
The AST-17D O2 sensor provides a reliable replacement option for several commonly used diving oxygen sensors, Teledyne Class R-17D, R17S, AII Model PSR-11-39JD, Vandagraph R-17VAN and Nuvair Model 9507.
Designed for Scuba Diving and Rebreather Systems
AST engineered this oxygen sensor specifically for scuba diving environments. It features a 3.5 mm mono jack electrical connection and an external housing with M16 × 1 front-end threads. These features allow secure installation in compatible rebreather oxygen monitoring systems.
Long Sensor Life and Stable Performance
Under ambient temperature and pressure conditions, the sensor delivers an expected operating life of up to 42 months. In addition, the proprietary electrolyte formulation and optimized anode material and its geometry maximize utilization of the lead (Pb) anode. This design extends sensor life, prevents signal drift, and reduces the need for frequent calibration.
Applied Sensing Technologies engineers and manufactures this and other scuba diving oxygen sensors in the United States.
